The founder of an infidelity website has claimed having the ‘perfect affair’ can actually save your marriage – which means do whatever you like, just don’t get caught.

Noel Biderman, who started the website Ashley Madison to allow married men and women to meet for discreet liaisons, says he is merely providing the technology to keep things secret and not encouraging people to be unfaithful.

‘There was tons of infidelity before I got here,’ said Mr Biderman, who refers to himself as the ‘Emperor of Infidelity’.

‘The only encouragement I give is to say to people there is a way to have the perfect affair [which is] not only meeting someone like-minded, it’s also not being discovered.’

The site, which now has 24million registered members and is launching in new global markets all the time, requires men to pay a subscription fee although women’s membership is free. The tag-line for the site is simple, but effective: ‘Life is short. Have an affair’.

And Mr Biderman, who is married himself, is honest about his own position.

‘If, in the next decade, my sex life evaporates I have no interest in being celibate,’ he told the Telegraph.

‘Because I have these wonderful children, an extended family I cherish, great economic success and homes – I have not worked for all of that just for sex. I wouldn’t get a divorce, therefore, if that happened, I’d try to have an affair.’
